Abstract
An apparatus and method for bi-directional format conversion and transfer of data between integer and floating point registers is provided. A floating point register is configured to store floating point data, and integer data, in a variety of numerical formats. Data is moved in and out of the floating point register as integer data, and is converted into floating point format as needed. Separate processor instructions are provided for format conversion and data transfer to allow conversion and transfer operations to be separated.
